PT-109 (1943)While on patrol in the Pacific during WWII, USS PT-109 was run down by the Japanese destroyer Amagiri. The much smaller American boat was torn apart by the impact, and two seamen perished. The surviving crew, commanded by future US President John F. Kennedy, swam to safety on a nearby island and survived on coconuts for days before Solomon Islanders scouting the area found them. Kennedy's actions made him a war hero. What did he use to send a message to Allies requesting a rescue?
